Error in progressEstimate

[Bilonik]

What happened?

When attempting to create a loading bar for the login process, the progressEstimate provided by the onProgressCallback of the Realm.open method fluctuates erratically. Instead of providing a smooth progression, the value jumps between 1.0 and lower values (e.g., 0.2, 0.21) repeatedly.

Repro steps

Implement the following code:
dart

final realm = await Realm.open(flexConfig, onProgressCallback: (syncProgress) {
    final processValue = syncProgress.progressEstimate;
    // syncProgress.progressEstimate keeps going to 1.0 then .2 then 1.0 then .21 and so on.
});

Observe the values of syncProgress.progressEstimate during the login process.

Expected Behavior:
progressEstimate should provide a smooth, incrementing progression from 0.0 to 1.0, allowing for the creation of an accurate loading bar.

Actual Behavior:
progressEstimate fluctuates between 1.0 and lower values (e.g., 0.2, 0.21), making it impossible to create a consistent loading bar.

Can you provide us with trace level logs from a fresh run of the app?

[Bilonik]

@nirinchev can you give me an email to send you the logs (i cant post them here).

It happens:

1. open a sync realm in a device.
2. Close the app
3. Make transactions on another device.
4. Open again the first device and listen to progressEstimate to create the loading bar.

You can send them to [email protected].

Looking at the logs, I don't see anything from sync - can you share the code you're using to setup the logger?

[Bilonik]

Realm.logger.setLogLevel(LogLevel.trace);
Realm.logger.onRecord.listen((event) {
print("Realm log message: '$event'");
});
